In a large saucepan, brown the meat (or the tofu) in 15 ml (1 tablespoon) of the oil, half at a time. Add more oil as needed. Reserve in a bowl.
In a food processor, dice all the fresh vegetables except the leeks.
In the same saucepan, add the rest of the oil and brown the chopped vegetables until they begin to brown.
Add the meat, tomato paste, tomatoes, broth, herbs, bay leaf, red pepper flakes and sliced leeks. Bring to a boil and simmer gently, stirring and scraping the bottom of the saucepan regularly for about 30 minutes to 1 hour 15 minutes or until the sauce thickens. Remove the bay leaf and serve over pasta of your choice.

Every year, we plant millions of Quebec leeks in the spring, which we harvest from mid-August onwards.
